Canadian firm South Bow has proposed reviving parts of the cancelled Keystone XL pipeline, potentially boosting Canada’s U.S. crude exports by more than 12%.
The project requires approval from President Donald Trump and additional pipeline links to major U.S. refining hubs.
Unlike the original Keystone XL, cancelled in 2021, the new proposal follows a different U.S. route after years of environmental opposition.
South Bow’s partner, Bridger Pipeline, filed plans for a 645-mile line from Montana to Wyoming, capable of moving 550,000 barrels per day.
However, Guernsey, Wyoming is not a final refining hub, meaning further connections to Cushing, Patoka, or the Gulf Coast would be required.
Analysts warn permitting risks and potential environmental litigation could delay or derail construction, particularly for new cross-state segments.
Even with Trump’s support, long-term political uncertainty remains, as future administrations could revisit approvals for large-scale energy infrastructure.
Meanwhile, competitors including Enbridge and Trans Mountain are advancing less complex expansions, intensifying competition in the North American pipeline market.
